Does Chicago have a subway system with a Metro Center station? An Old Town area & Historic District and an historic Cathedral or very unusual old church? A large park with a decorative winding creek? This has been part of a recurring dream of mine since the late 1990s. Associated it more with WashDC than Chicago but the Great Lake just "rang a bell".

My only experience with Chicago has been the airports and RTC/NTC which is a bit away. That and the little town of Zion, and Waukegan.
